Enphase IQ Battery 10C 5.0kWh Battery Unit B05-C01-US00-1-3 LFP AC-Coupled Solar Battery Module

This listing is for ONE 5.0kWh battery unit. A complete IQ Battery 10C requires two battery units plus the IQ Battery 10C cover kit (B10C-NC-0708-O), sold separately. System specifications below apply to the complete IQ Battery 10C. For permitting and interconnection, use model number IQBATTERY-10C-1P-NA.

The Enphase B05-C01-US00-1-3 is a 5.0kWh lithium iron phosphate (LFP) battery unit for the Enphase IQ Battery 10C, an all-in-one AC-coupled home energy storage system. Two of these battery units, combined with the IQ Battery 10C cover kit, form one complete IQ Battery 10C with 10.0kWh of usable capacity and four embedded, grid-forming IQ8B Microinverters.

The complete IQ Battery 10C delivers 7.08kVA of continuous power, provides backup capability during grid outages, and is backed by Enphase's 15-year limited warranty, making it a reliable choice for homeowners and installers building a residential Enphase Energy System.

Safe LFP chemistry

LFP (lithium iron phosphate) is one of the safest and longest-lasting chemistries for daily solar storage. The IQ Battery 10C is evaluated to UL 9540A for thermal runaway fire propagation, cools passively with no moving parts, and operates from -4°F to 131°F (-20°C to 55°C) when discharging.

Key Applications

• Home backup power: Keeps essential loads running during grid outages when installed with the Enphase Energy System.
• Solar self-consumption: Stores excess solar production for use in the evening or at night.
• Time-of-use savings: Supports TOU and NEM integrity modes to reduce reliance on grid power during expensive peak hours.
• Building or expanding an IQ Battery 10C: Pair two battery units with the IQ Battery 10C cover kit to complete one system.

System compatibility

The IQ Battery 10C is compatible with Enphase IQ and M Series Microinverters, the IQ Meter Collar, IQ Combiner 6C, and IQ Gateway for grid-tied and backup operation. Homeowners can monitor and control the system remotely through the Enphase App, and installers can manage it through the Enphase Installer Platform.

Certifications

• System: UL 9540, UL 9540A, UL 1741-SA/SB, IEEE 1547:2018, UN 38.3, NEMA Type 3R
• Cell module: UL 1973, UN 38.3
